To .all whont it 11i/Cty concern:

Be it known that I, ISIDOR NASCE, a subject of theQueen of Great Britain, residing at Lonthe loop of thread thus formed can be usedA for hanging np the card or for connecting sheets of paper together, or for any other useful or ornamental purposes; and it is to'beunderstood that the expression herein used of cord or thread applies to a ribbon or string or similar liexible materials and that the present invention is avaiiable'for tying a loose loop by which a calendar, card, or other article' may be'hung up, or for tying a loop that passes comparatively tight around the fold of a signature at either the top or bottom,or both', for con nectinganumber ofsheets togetheigsuch as in a weekly periodical, the

act of tying being the same in both instances 5. but in one case the thread is drawn up closely,.

while in the other instance itis spread by a thumb, so as to be loose around the edge of the article.

In carrying out this invention I make use of a bed upon which the article to be strung is laid,and a reciprocating eye-pointed needle is made use of withthe thread, cord, or string passing through the eye, and theoperations performed are in the following order: A pair of lingers grasps the thread near the end and beyond the eye of the needle. These lingers carry the end of the thread down through an openingin the bed of the machine. A second' set of fingers below the bed grasps the thread and takes it from between the first lfingers. and carriesit along nearly horizontal. A third pair of fingers that oscillate passes around and grasps the threadand takes it from the second lingers and carries the thread around the eye-pointed needle, that at this time has passed through the paper or other material. 'lheeye-pointed needle-rises slightly to form a loop of its thread and the second pair of fingers upon a return movement passes through i this loop at the needle and grasps the thread from the oscillating fingers and draw the same back through the loop of thread at the needle, and the needle rising tightens the knot thus tied and a knife cut-s oit the thread simultaneously with the grasping of the thread by the first pair of lingers, which at this time has returned above the bed and is in position to receive the-thread as it passes from the eyepointed needle to the knife that eects the separation of such thread. The article thus tied by a loop of string or thread is removed, another' one placed in position, and the operations are repeated.

Where the loop is left loose around the edge of the card or other 'materiah a thumb beneath the bed is projected across the slot in the bed, so that the loop is tied around this thumb as it is drawn up, and then theV thumb is withdrawn to allow the loop to escape through the slot in the bed.

' In the drawings, Figure l is a side View of the machine. Fig.` 2 is an inverted plan. Fig.' 3 is a diagram representing the mechanism that reciprocates the eye-pointedneedle. Fig. 4 is a diagram representing the mechanism that actuates the rst pair ofk fingers.

Fig. 7 is a diagrammatic side view of the mechanism that aot'uates the third or oscillating pair of fingers and a section of the. bearing for the shaft carrying the same. Fig. S is a diagrammatic viewoil the mechanism for actuating the thumb. Fig. 9 is an,

lelevation of the meohanism'for the third pair of fingers at right angles to Fig. 7.. Fig. 1Q shows the end of the arm, knife, and presserfoot. Fig. 1l shows part'of thejend of the arm and the first pair of lingers, the presserfoot being removed. Fig. l2 is' a section at the pivot of the first pair of fingers. Fig. 13 is a detached plan of the second pair of 1ingers. Figs. 14 to 2l are diagrams representig the formationof the loop; and Fig. 22 is a planof the third fingers, the position of the slot in the bed being indicated by dotted lines.

AThe bed A is of ordinary character, and the hollow arm A is adapted to receive the der e gers.

e ceases vices hereinafter described, and the needlebar B slides iny bearings at the end of the arm A', and the eye-pointed needle b is at theend of the needle-bar B, and the thread or similar fibrous material is supplied from the spool C and passes through a suitable tension device c and through the eye of the needle b.

The first pair of fingers D is mounted upon a finger-bar D', that slides through a rocking head D2, that is pivoted at 5 near the end of the hollow arm A. This first pair'of fingers D has to be opened and closed at the proper times, and after the thread has been grasped by this pair of lingers said lingers pass down through a mortise 6 in the bed A, and the fingers are opened at the proper time to drop the thread after the second pair of lingers has grasped the same, and the lirst pair of lingers rises through thefbed and returns to its first position, and these movements are to be given byany desired mechanism. I have, however, represented means for rockingthe head D2 and also for raising and lowering the lingerbar and for opening and closing the lingers.

The lever E is slotted at its upper end and acts upon a stud or roller upon the linger-bar D' to raise and lower the same at the proper time and carry with it the lirst lpair of lingers,

and there is a head E upon the lower end of the linger-barD', upon which the lingers D are carried, and the cam F upon the driving-r f shaft G gives motion to the lever E at the proper time for raising and lowering the lin- The moving `linger is closed by the spring 7and it has a projection 8 that comes in contact with a stationary arm 0 to open the ingerat t-he proper time when the lingers have carried the thread below the bed, and it has another projection 10 to come in Contact with a stationary arm 11 to open the lingers as they go forward to grasp the thread close to theeye-pointed needle and just before the thread is cut. i

There is a cam H on the driving-shaft G, acting upon a lever I, and there is a rod I', extending longiludinally through the hollow arm A' to the rocking head D2, and the spring I2 keeps the lever against the cam and moves the rocking head in one direction. The movements of these parts are as follows: The arm 11, acting on the projection 10, opens the moving linger when the first pair of lingers is in `the elevated position above the bed, and the cam H acts on the lever I and swings the head D2, carrying the fingers D open against the thread as it passes from the eye pointed needle, and the projection 10 slips off the arm 11 and allows the spring 7to close the lingers and grasp the thread, and a continuance of the movement of the rocking head brings the lingers over the mortise 6, and the cam Fnow acts upon the lever E and carries the fingerbar D' and lingers D down through the mortise 6, and the second pair of lingers, hereafter described, grasps the thread in the tirst pair of fingers D just before the projection 8 comes in contact with the stationary arm 9 and opens the lingers D to drop the thread, and these lingers D now return to their lirst position. The cam J, .acting upon the lever K, carries the needle-bar B downward and perforates the paper or other material with the eye-pointed needle l). Thereby the thread is carried double by the needle through the card, paper, or other material, and such cam J causes the needle-bar to rise slightly to throw out the loop of thread, and then holds ther needle in its depressed position during the operations hereinafter described in tying the knot, and then the needle rises to the normal position. The second pair of fingers L is carried by a lever L', pivoted at 12, and the position of this pivot is such thatin the swinging ot' the lever the second pair of lingers L is moved longitudinally of the machine and parallel, or-nearlyso, with a slot that extends from the' mortise 6 to the hole through which the eye-pointedneedle descends. Any snitable mechanism may be made use ot' for moving the second pair of lingers and for opening and closing the same at the proper time. I have represented a bent lever L2, pivoted at 13 and havinga connecting-rod 14 to the levery L', and the cam M upon the driving-shaft G acts upon the bent lever L2 to give to the parts the proper motions at the proper times. The spring 15 acts to press the bent lever L2 toward the cam and to move the second pair of lingers in one direction.

One linger of the pair ot lingers L is pivoted at 16 and has a tail 17, bywhich the finger is opened or-closed, and this tail is acted upon by a lever N, pivoted upon the lever L', and the lever N' and cam N2 on the shaft Gserve t0 act upon the tail 17 at the proper time to open the second pair of lingers, there being a spring 18 to close the fingers when not otherwise acted upon. e

` It will be seen that the points ol" the lingers L are toward the shaft G, and the shapes of the cams are such that when the first pair of lingers D has carried the thread down through the mortise 6 the second pair of lingers L passes along and grasps the thread slightly above the lingers D and between the same and the bed A, and at this moment the lingers D open and the lingers L close and the thread isdrawn along nearly horizontally into the lingers, assuming the position represented in Fig. 2, ready for the third or oscillating-pair of lingers to take the same, as hereinafter described, the second pair of lingers opening and remaining in position to pass through the loop of thread at the needle and catch the end of the thread froxnthe oscillating lingers and draw the same through the loop in tying the knot, as before intimated.

The third set of lingers which oscillate are made as segments of circles, as shown at O O. The shank of the linger O is connected with the shaft P, and the finger O' is connected to the sleeve P', around the shaft P, and the spring 19 tends to close the fingers, and the llever Q, with a forkacting upon the sleeve P', tends to openthe lingers, and this lever -hold them in the proper lrelative positions,

and the shaft P is supported in a suitable hearing 22, in which it can revolve and also be moved longitudinally, and the pinion R is. :held between the parts of the bearing 22 and has a feather by which the shaftlD is rotated,

and this pinion Ris acted upon bya segmental-rack R', so as to partially revolve the pinion, the shaft, and the ilngers,and this segmental rack R' is upon a leverpivoted at 23 and having an arm against which the cam R2 acts, there being a spring 2i that lturns the segmental rack, pinion, and lingers in one direction, the cam R2 turning the parts in the other direction. y

An end mot-ion vertically is given to the shaft P by a lever S, pivoted at 25, there being aspring 26 acting against a collar to move the shaft P downward, and the lever S raises the shaft at the proper time against the action of the spring, and a lever S' and cam S2 act upon the lever S to give the required motions at the proper time; Y

The motions given to the oscillating fingers O O' by the before-named parts are' as follows: As the second pair of fingers L draws 'ihem.

the thread along below the bed the fingersvv O O' are moved lip-toward theunderside of .the bed and swung around so as to be above the thread, and then the lingers O O' are moved downward away-from the under side of the bed and opened and at the same time they are turned so that the thread passes in between the ends of these lingers O O' and the fingers close, grasping the thread between Then these lingers O O' carry the thread across the path of the eye-pointed needle, holding the thread while the eye-pointedl needle descends, and then the fingers 0.0 oscillate backward and carry the thread around the eye-pointed needle and hold thesame while the eye-pointed needle rises slightly to throw out a loop of' thread adjacent to thevneedle, and the second painof tin gers L passes through the loop` andthey open and then close, grasping the thread as it isheld by the lingers O O', and these lingers O O' now open and release the thread, leaving such thread in the grasp of the second pair of lingers L, thatV` now move backward and draw thethread Vthrough the loop adjacent to the eye-pointed needle, and such eye-pointed needle draws up, shedding off the vloop that had been wrapped around it by the oscillating fingers and causing the knot to be tied bythe drawing up of the eye-pointed needle.

. It will be apparent that if only the devices thus far described were employed the thread would draw 'against the edge of the card or other article lying upon the bed A and that the knot would be tied with the thread comparatively tight as the eye-pointedneedle draws up through the card or other material,

the second pair of fingers L holding on to the -v end of the thread as the knotis tightened -by the'drawing'up of such eye-pointed needle, and in this manner the loop of thread tied might be employed for-joiningsheets together,

or it might be employed at the top or bottom or at firstone and then the other of a folded signature for connecting the sheets together; but where the loop is to be slack, so that it may be used for hanging up a card, calendar, or other article, a thumb T is made use of, the same being upona block T' and moved by a lever T2, spring, and cam T3,so that the thumb is passed across the slot through the bed previous to the thread being carried down through the mortise 6 by the first pair of fingers D. Hence the thread is around this thumb at the time the knot is tied, after which thev cam T3 causes Ithe withdrawal of the thumb, so that the loop of thread in'a loose condition is free todraw up through the slot in the bed when the card or other article is removed from lthe surface of the hed.

'It is radvantageous to'employa stop 27, against which the card `or other article is laid upon the bed A, so as to Vdetermine the position of such card or other article in relation to the eye-pointed needle for such needle to pass through at the proper place,and a presserfoot U is made use of upon a bar U', thatis pressed down hy a spring 28, and there is a knob 29 or` projection by which the presserfoot can be lifted for inserting or removing the'card or other article through which the cord or string is passed and tied, as aforesaid, and it is necessary to cut the cord or string after the knot has been fully tied, and with lthis object in view a knife V is provided upon a har V', that is pivoted vat 30 upon theend 'of the arm A', and the spring 3l moves the knife and bar in one direction, and there is a leverV, having a roller or stud 32, that acts against the bar V' to move the same, and this lever'ViT receives its motion from a lever W'and cam VW, and the bar V' isnotched near where the stud 32V acts upon the same, so that the spring 31 canvdraw the knife back out of the way while the eye-pointed needle rises and Athe* first pair of lingers D passes along and grasps the thread that descends from the eye-pointed needle to the card or other article that has been perforated, and as these fingers D draw backwith the thread; pulling the same through the eye of the needle, the bar V' and knife pass forward and in contact with the thread, so as to cut the same between the fingers' D and the bed, and as this operation is performed the lever W acts upon the projection 29 of the bar U',lifting the presser-foot U, so as to relieve the card from its holding action and allow the card or other article to be lifted /off and an:`
